遵循步骤:

Use MySql commands as follows, for converting to InnoDB (ALTER TABLE t1 ENGINE = InnoDB) or (ALTER TABLE t1 ENGINE = MyISAM) for MyISAM (You should do this for each individual tables, t1 is for the table name.). Write a script that loops on all tables and run the alter command Use an already available script to handle that: https://github.com/rafihaidari/convert-mysql-tables-storage-engine Try this SQL to Get all info will get all the tables information then you can change all the table from isam to InnoDB SELECT CONCAT('ALTER TABLE ',TABLE_NAME,' ENGINE=InnoDB;') FROM INFORMATION_SCHEMA.TABLES WHERE ENGINE='MyISAM' AND table_schema = 'your_DB_Name';

要为所有非系统模式中的所有表生成ALTER语句，按这些模式/表排序，运行以下命令:

SELECT  CONCAT('ALTER TABLE ',TABLE_SCHEMA,'.', table_name, ' ENGINE=InnoDB;') AS sql_statements
FROM    information_schema.tables
WHERE   TABLE_SCHEMA NOT IN ('mysql', 'information_schema', 'performance_schema', 'innodb', 'sys', 'tmp')
AND     `ENGINE` = 'MyISAM'
AND     `TABLE_TYPE` = 'BASE TABLE'
ORDER BY TABLE_SCHEMA, table_name DESC;

之后，通过客户端运行这些查询来执行修改。

答案基于上述答案，但改进了模式处理。

在phpMyAdmin中使用此sql查询

SELECT CONCAT('ALTER TABLE ',table_schema,'.',table_name,' engine=InnoDB;') 
FROM information_schema.tables 
WHERE engine = 'MyISAM';

只是测试了另一种(简单的?)方法，对我来说很有效。

只需导出您的DB为.sql文件，编辑它与gedit或记事本;

将ENGINE=MyISAM替换为ENGINE=INNODB并保存已编辑的文件

编号或替换完成应该是你的表的编号

导入到MySQL (phpMyAdmin或命令行)

瞧!

还有另一种选择……下面是如何在ansible中做到这一点。它假设数据库的名称在dbname中，并且您已经配置了访问权限。

- name: Get list of DB tables that need converting to InnoDB
  command: >
    mysql --batch --skip-column-names --execute="SELECT TABLE_NAME
    FROM information_schema.TABLES
    WHERE TABLE_SCHEMA = '{{ dbname }}' AND ENGINE = 'MyISAM';"
  register: converttables
  check_mode: no
  changed_when: False

- name: Convert any unconverted tables
  command: >
    mysql --batch --skip-column-names --execute="ALTER TABLE `{{ dbname }}`.`{{ item }}` ENGINE = InnoDB;"
  with_items: "{{ converttables.stdout_lines }}"

这很简单。只有两步。

复制，粘贴并运行: SET @DATABASE_NAME = ' name_your_db '; SELECT CONCAT('ALTER TABLE "， table_name， ' ENGINE=InnoDB;') AS sql_statements FROM information_schema。TABLE AS tb WHERE ' ENGINE ' = 'MyISAM' AND ' TABLE_TYPE ' = 'BASE TABLE'

(复制粘贴所有结果在SQL选项卡)

将所有结果复制到SQL选项卡并在下面一行中粘贴。 开始事务; 提交;

例如:

START TRANSACTION;
ALTER TABLE `admin_files` ENGINE=InnoDB;
COMMIT;
